To all whom it'may concern.' Y =-Be it known that we, FRANK PnARsALL TAYLOR and Louis HENRY Hari, citizens of the United States, and .residents of the borough of Brooklyn, Acounty of Kings, city and State of New York, have invented certain new 'and useful Improvements in the AMethod of Making Box-Liners, of which the following is a specification.

This invention relates to a device Commonly termed a box liner. A device inserted --inside of a commonrwooden box-.to protect `the contents'of the boX from dampness or oxidation or other change in the .contents that might be occasioned by atmospheric `iaction. Y

In the past it has been customary to make box liners of sheet tin, sheet lead,.or, other which substances are -lapping portions of the liner arefolded upon and are'soldered.

It is obvious that when liners are used for certain materialsA such as gun cotton, explosives or even certain food products it is not practical'to solder theclosing portion or top as the presence of the necessary lheat would be dangerous or unsatisfactory because ofthe changethatvtheheat would produce in the contents of the box.

\ Another objection which .our device is intended to overcome is the exceeding high cost of metallic box liners. Y

We have produced a box liner which fulfils all'of vthe requirements and is veconomical of construction, and easy and V.satisfactory of o eration. The device and its method of app ication will be described as the specificawhich our liner is produced.

The remaining yfigures are on a small scale, andare intended as diagrams. y

Similar reference-.numerals indicate like parts in all of the figures where they appear.

In producing our box liner y,we obtain a plurality of sheets of suitable.k paper of any desired area. In the drawings the sheets are shown as oblong, andthe box into which the Vliner isintroduc'ed is also oblong.

Ve take the two sheets of paper indicated at 1, and 2, and secure them together by means of Ya waterproof cement 3, and

to Vone side of one sheet of paper been heated to a liquid paraffin which has this exposed surface of state, and we give vone sheet a thorough and comparatively heavy coating of paraffin as indicated at 4 in Fig. 2. y 1

1When theparafiin is hard kand dry we cut from the sheets previously securedy together and coated ablank of a desired size as shown in Fig. 1.

Ve next obtain a mold or shaping device such as a block or box of desired area, an area just suiicient to fit loosely within the formed, and placing the sheet, paraliin side downward, upona table orf other support, we arrange the mold or die centrally upon the sheet so that it will occupy that space bounded by the lines 5, 6, A7 and 8 of the blank shown in Fig. 1. We then turn upward the four sides of the sheet upon the lines 5, 6, 7 and 8, and this will cause the the free portion of the sheet as indicated by thelines 9, 10, 11, i2, is, i4, i5 and i6.

The shape of` the 'sheet inclosing the mold will then have the appearance of the f within the liner.

diagram Fig. 3, the portions 17 and 18 being the projecting ends.

The next step is to fold the ends 17 and 18 inward, the end 18 being turned inward upon 'the end of the moldandthe portion 17 folding over that portion 18. Before this fold is lmade we apply a waterproof cement between the two portions of the projecting ends 17 and 18and all similar ends. That is, we cement the interior surface of the oblong areas bounded by the lines 9 and 10, 1l and 12, 18 and 14, and 15 and 16 and the adjacent outer edges; The inward movement of the ends will produce the diagonal folds 19, r20, 21 and 22.

Under each of the inturned portions 17 and 18 we place a coating of waterproof cement such as we have previously used, and we force the ends firmly inwardupon the cement so that the joints will be tight, and the portions adjacent to each other will be completely cemented together. j

We call particular attention to the fact Vthat theends and the overlapping [portions of each of the ends 17 and 18 extend Vupward abovethetop' line23, of the mold or-form. f f y When the device is produced as described itis ready to be inserted into the box which it is to line. We, therefore, withdraw the lmold from the open top of the shaped liner, andl in this condition the liners may be shipped to their destination for use.

When' it is desired 4to 'use aliner produced 'according to our method the box is prepared, a liner introduced therein, and-'the material intended for the box is placed When the box is prop-` erly filled we place a sheet of the same duplex paper from which ythe liner has been produced across the contents ofthe box, tak-` ing care that the paraiin surface iny nonadjacent Y'to the content of the box.

The ends of the liner are .now turned inward as indicated by the dotted lines 24 and 25 in Fig. 6, and then the sides are folded and turned inward as indicated by the lines 26, 27, 28 and 29. A coating of cement is placed under the inwardly folded ends 24 and 25, Vand the inwardly folded sides and when pressed firmly downward are caused'to adhere to each other and to the body of the liner. j f

We now take a second sheet of; paper of Y. the area ofthe top of the box, and after having applied to the inturned ends and sides a thorough coating of the cement we place Ythis top sheet 29 over the inturned ends and sides, and press it firmly downward. This contemplates the formation and closing of Your liner, and the topt of the box may be attached in ,the ordinary manner.

The cement used in the' production` of' our liner must necessarily be of Waterproof ce- :cation of the internal sheet indicated, bythe t dotted line 30 in Fig. 5, and the fact thata comparatively' low` heat may be employed with the cement used by us will make it practical to use that ffcement even yfor the purpose of closing the openl end of the containenf It is obvious that in forming the-container we also produce the .sheets729 and 30.-; Itis also obvious that-wemay form our box liner from a material-such as paper and `fabric Y cemented together or. from any other similar and cheap materials that; can be made thoroughly waterproof. f: s v

Shouldit 'be desired-to re'tainmoisture within the material contained within the box the liner will be made in a manner differing from that-described. only to theextent that thel parafin containing surfacev i will be interior of the`liner instead 0f eX- terior as described. v

' Modifications in the shape or the application 'of our device mayV be madewithin the scope of the appended claims without departing fromthe principle orsacricing I the -advantagesof the invention.
